obviously one delay is more memorable than 10 arrivals on time.

Our brains are wired to remember negative outcomes to help decision making in the future. Which is why I was asking, I didn’t have a great opinion of it, and just wanted to be sure I wasn’t being needlessly harsh.
Which it seems like I was… considering I live in the UK and rail travel here is an absolute joke. No reason the train from Edinburgh to London should be 5ish hours and 7ish to drive. It’s not even really that far…I say as a Canadian with a probably quite skewed perception of reasonable distances to drive…

How often is it running on time with no issues?
Legitimate question, I only took it once from Frankfurt to Cologne, and it was ok once we were onboard, but was massively delayed. Just curious if that was an outlier or a regular thing.
